Standard 623ZZ ball bearing flange

thingiverse

Here are some F623ZZ flanged bearings for my Kossel printer build, but instead I received standard 623ZZ bearings by mistake. I decide to use them and design this simple part as a flange for the bearing. The inside of it is tapped with M3 thread so they will stay firmly in place. I attach these using an M3 thread that has been tapped inside. This way you can tighten them up against the printed bracket, keeping them secure without wobbling around. There's also a shoulder on them to contact the inner race, allowing the bearings to always spin smoothly and freely.
